"""
loader.py

The loader has to load the signature module completely at startup,
to make sure that the functions are available when needed.
This is meanwhile necessary to make the '__doc__' attribute work correctly.

It does not mean that everything is initialized in advance. Only the modules
are loaded completely after 'import PySide2'.

This version uses both a normal directory, but has also an embedded ZIP file
as a fallback solution. The ZIP file is generated by 'embedding_generator.py'
and embedded into 'signature.cpp' as "embed/signature.inc".

Meanwhile, the ZIP file grew so much, that MSVC had problems
with it's 64k string limit, so we had to break the string up.
See 'zipped_string_sequence' in signature.cpp.
